Is anyone going to recognise this election?
There will be a few countries, particularly in Africa, that will support Mugabe either because they dislike the pressure from Europe and America, or because they cannot claim to hold democratic elections themselves.
A key moment will come on Monday: Mugabe has said he will attend an African Union summit in Egypt to challenge his critics, and other African leaders may be forced to choose whether to back him or snub him. All eyes will be on Thabo Mbeki, South Africa's president, who up to now has been Mugabe's most powerful and reliable friend. Even countries that have denounced the elections are likely to maintain diplomatic relations with Zimbabwe, on the grounds that those relations are with the country not the government. Britain and others will try to strengthen ties to the opposition MDC on the grounds that it won the parliamentary vote in March.
What happens next?
Mugabe has said he will enter into talks with the opposition after the vote, suggesting that he would try to form a "government of national unity" by coopting some members of the MDC. There could be reprisals against those who refuse to take part, and against Zimbabweans who do not have ink on their fingers showing they have voted.
Was it possible to vote MDC?
People could have voted for the MDC's leader, Morgan Tsvangirai, whose name remained on the ballot, despite his withdrawal. But few would have taken the risk.
Were there election monitors?
The regional group, the Southern African Development Community sent more than 200 observers to the elections and Zimbabwean pro-democracy groups also tried to field observers although they met repeated bureaucratic obstacles. But the observers could not move freely, particularly in the areas that had witnessed the worst pre-election violence.
Are there divisions within Zanu-PF?
Zanu-PF is deeply divided over the course Mugabe is taking. One of the vice-presidents, Joice Mujuru and her husband Solomon are thought to lead one of the factions in the party's politburo. Another is led by a former finance minister, Simba Makoni, who stood against Mugabe in the first round of the presidential elections. But since the election loss in March, the politburo has ceded power to a narrower group of hardliners and generals in joint operations command, led by Mugabe's lieutenant, Emmerson Mnangagwa.
